Abstract

The invention provides a shear-resistant type dodecagonal self-locking nut for a space navigation structure and a processing process for the shear-resistant type dodecagonal self-locking nut. The shear-resistant type dodecagonal self-locking nut comprises a close-up table, a dodecagonal supporting table and an inner threaded hole, wherein the close-up table is a close-up table with taper; a wide-mouth end of the close-up table is connected with the dodecagonal supporting table; the close-up table is coaxial with the dodecagonal supporting table; the inner threaded hole is formed in the close-up table which takes the axis as an axle center; and the inner threaded hole penetrates through the dodecagonal supporting table. The shear-resistant type dodecagonal self-locking nut provided by the invention has the advantages such as great wrenching torque, a small structural size, light weight, looseness prevention and reliability, high strength, good heat and corrosion resistance and excellent anti-fatigue performance, and can be popularized and applied to important supporting-shearing structures in the field of weapons and equipment such as aerospace, engines, ships and nuclear energy.

Description

technical field [0001] The invention belongs to the technical field of fasteners and their production and manufacturing, and in particular relates to a shear-resistant twelve-point self-locking nut for aerospace structures and its processing technology. Background technique [0002] With the development of the aerospace industry, the high-temperature corrosion environment represented by aerospace has put forward more and more stringent requirements for fasteners. The need for high-performance fasteners is becoming more and more urgent. [0003] The threaded connection structure of mechanical equipment generally adopts hexagonal nuts and external threaded fasteners to be used together, and according to the different bearing capacity and the requirements of the use occasion, the nuts are designed as ordinary hexagonal nuts, hexagonal lock nuts, thin hexagonal nuts, and thick hexagonal nuts. Nuts, hexagonal slot nuts and other forms are often used together with washers, but du...
